AMD Ryzen Embedded 9900X vs Intel Core Ultra 7 258V Comparison

Head-to-Head Benchmarks

The Intel Core Ultra 7 258V arrives with a full suite of recorded benchmark scores, while the AMD Ryzen Embedded 9900X has no benchmark entries in the database at this time. This asymmetry means the head-to-head comparison relies entirely on the Intel part's measured results and its position relative to other processors in the database.

The Intel Core Ultra 7 258V holds a percentile ranking of 74 against all CPUs, with an average benchmark score of 20,454. Its nearest rivals in the database are tightly clustered: the AMD Ryzen 5 5600 scores 20,468, just 0.1% higher, while the AMD Ryzen 5 8500G trails by 0.1% at 20,425. The AMD EPYC 9454P and AMD EPYC 7713 follow at 20,422 and 20,363, respectively, putting the Intel part within 0.4% of all four competitors. This places the 258V in a narrow performance band where a few points separate it from its closest neighbors.

Looking at the multi-core results, the Cinebench R23 multi-core score of 10,301 shows a strong throughput capability for an 8-thread mobile processor. The Geekbench multi-core result of 9,325 reinforces this pattern. The PassMark multi-thread score of 18,887 aligns with the same picture. Single-core performance is equally notable: the Cinebench R23 single-core score of 1,872 and the Geekbench single-core score of 2,100 indicate a well-optimized single-thread design. The PassMark single-thread score of 4,018 confirms this consistent strength.

The specialized PassMark workloads reveal where the architecture excels. The data compression score of 176,686 is the highest of the PassMark sub-tests, while floating-point math reaches 57,372. Integer math follows at 42,889. Random string sorting produces 21,580, and extended instructions deliver 14,717. Data encryption completes at 13,534. The physics test yields 1,565, and the find prime numbers test produces 185. These figures sketch a processor that handles compression and math-heavy tasks with particular efficiency.

The critical observation for the head-to-head is that the AMD Ryzen Embedded 9900X currently has no benchmark scores, no wins, and no rival listings in the database. The Intel part has 19 recorded benchmark entries. Any direct comparison of measured performance between these two specific parts is therefore impossible from the recorded data. The database shows the 258V performing at a level consistent with mid-range desktop processors like the Ryzen 5 5600, but it offers no comparable numbers for the 9900X.

Architecture Differences

The two processors come from opposite ends of the computing spectrum. The AMD Ryzen Embedded 9900X uses the Granite Ridge codename with a Zen 5 architecture, manufactured on a 4 nm process by TSMC. It packs 12 cores and 24 threads. The Intel Core Ultra 7 258V uses the Lunar Lake architecture, built on a 3 nm process also by TSMC, with 8 cores and 8 threads. The process node difference is small, but the core and thread counts diverge sharply: the AMD part offers 50% more cores and three times the threads.

The cache layouts differ substantially. The AMD part allocates 80 KB of L1 cache per core and 1 MB of L2 cache per core, with a large 64 MB L3 cache. The Intel part provides 192 KB of L1 per core and 2.5 MB of L2 per core, but only 12 MB of shared L3. The AMD processor clearly favors a large shared last-level cache, while the Intel design relies more on per-core L1 and L2 capacity. The transistor count for the AMD part is listed at 16,630 million, with a die size of 2x 70.6 mm². The Intel part has no transistor or die size data in the database.

Clock speeds tell another story. The AMD Ryzen Embedded 9900X runs at a 4.40 GHz base clock and boosts to 5.60 GHz. The Intel Core Ultra 7 258V runs at 2.20 GHz base and 4.80 GHz boost. The AMD part holds a substantial clock advantage in both states. Power envelopes also differ enormously: the AMD processor carries a 120 W TDP, while the Intel part draws just 17 W. This reflects the market segment split, with the AMD unit aimed at desktop and the Intel unit at mobile.

Memory support diverges as well. The AMD part supports DDR5 with dual-channel memory and a bandwidth of 89.6 GB/s, plus ECC memory capability. The Intel part supports LPDDR5X with dual-channel memory and a higher bandwidth of 136.5 GB/s, but no ECC support. The Intel part's higher bandwidth with a lower power envelope suggests an integrated memory controller optimized for low-power operation. The AMD part's ECC support points to embedded and server-adjacent workloads where data integrity matters.

PCIe connectivity differs sharply. The AMD Ryzen Embedded 9900X provides Gen 5 with 24 lanes from the CPU alone. The Intel Core Ultra 7 258V provides Gen 5 with only 4 lanes. The AMD part offers six times the PCIe lane count, a decisive advantage for expansion-heavy systems. Integrated graphics also differ: the AMD part uses Radeon Graphics, while the Intel part uses Arc 140V.

The sockets reflect the intended platforms. The AMD processor uses AMD Socket AM5, a socket designed for desktop and embedded boards. The Intel processor uses Intel BGA 2833, a soldered mobile package. The multiplier is unlocked on the AMD part, allowing overclocking, while the Intel part has a locked multiplier. The AMD part's production status is Active, as is the Intel part's. The release dates differ by just over a year: the Intel part launched on 2024-09-23, and the AMD part on 2025-10-06.

The Verdict

The recorded data supports no direct performance verdict between these two processors because the AMD Ryzen Embedded 9900X has no benchmark scores in the database. The Intel Core Ultra 7 258V, however, demonstrates a clear performance profile from its 19 recorded benchmarks. It sits at the 74th percentile against all CPUs, with an average score of 20,454, placing it within 0.4% of four close rivals including the AMD Ryzen 5 5600 and the AMD Ryzen 5 8500G.

For workload suitability, the choice depends on the platform requirements. The AMD Ryzen Embedded 9900X targets desktop and embedded systems with 12 cores, 24 threads, a 120 W TDP, DDR5 with ECC support, and 24 PCIe Gen 5 lanes. These specifications suit multi-threaded server-like workloads, memory-integrity-sensitive applications, and expansion-heavy configurations. The unlocked multiplier allows tuning. The large 64 MB L3 cache benefits workloads with high data reuse.

The Intel Core Ultra 7 258V targets mobile systems with 8 cores, 8 threads, a 17 W TDP, LPDDR5X memory at 136.5 GB/s, and 4 PCIe Gen 5 lanes. Its higher memory bandwidth relative to its power envelope and its strong single-core scores suit latency-sensitive and battery-conscious applications. The locked multiplier and soldered BGA package indicate a fixed, integrated design.

The database shows one processor with a full set of measurements and another with none. Buyers can rely on the Intel part's recorded performance, which confirms parity with established mid-range desktop processors. The AMD part's specifications indicate a different class of system entirely, but its measured performance remains unquantified in the database. The verdict, strictly from the data, is that the Intel Core Ultra 7 258V is the only one of the two with verified benchmark results, while the AMD Ryzen Embedded 9900X offers a broader core, cache, and PCIe footprint on paper.
